Portable Diagnostic Systems LLC (“PDS”) is a biotech startup developing a next-generation microfluidics-based drug testing platform for law enforcement that takes the guesswork out of impaired driving traffic stops. This saves police departments both time and money, and reduces the amount of false positives which may cause an individual, who is not impaired by a drug, to have to go through the unnecessary hardship of arrest, lengthy medical exams, and warrant ordered blood draws for toxicology testing.
